This roughly corresponds to the figures given by McHenry. Kronosaurus (and P. funkei and kevani) 10-11 m; 9-12 tonnes, mean estimate MoA 12 m; 15 tonnes and P. macromerus 13 m; 20 tonnes.

Looks like I underestimated the skull size of Pliosaurus. When I read the 2 m skull length figure in the Pliosaurus kevani description, I didn't realize it is the lowest measurement.

coherentsheafI must have missed your posts regarding the size of P. funkei. Thank you for your review

Since I have these four silver stars I felt that I had to upload something already, I've been working on an skeletal of Patriofelis ferox, mainly so I can have something to reconstruct the skull of Sarkastodon, scale how big is the skull in proportion to its body and give it an outline. I still haven't finished the skeletal of Patriofelis ferox but I think the rigorous version of Sarkastodon is good enough as it's mostly black outline haha I won't be uploading this one to deviantart, the one I'll upload will have the complete Patriofelis skeletal too so it's clear that I didn't got the proportions and outline out of thin air. So now I present you the giant bone crushing creodont otter of doom.  |

 Another generic scale chart: possible largest theropod and possible biggest sauropod. The Spinosaurus is based on Hartman's estimate (11 % bigger than holotype), which is close to mean estimate (between 0% and 20% larger than holotype of S. aegyptiacus), i know it doesn't mean necessarily most accurate due the dentary of BSP may not fit perfectly to MSNM v4047 rostrum. Even if 20 % scaled up dentary would fit good in length, but it would very oversized in windth, while normal scaled dentary would be too short, but fit well in windth. Although it may belong to different taxon, but the skull differences appears as well in animals from even the same species for example in Tyrannosaurus rex and Allosaurus fragilis specimens. The Amphicoelias size is based on newest Zach's average estimate. I am not sure Hartman Diplodocus is really CMNH 84 though. So i suspect i probably made an mistake. The length from tip to tip is around 50 m and even more when we straighten the tail. Using Paul's estimate from 1994 (11.5 tonnes), Amphicoelias fragilimus would be roughly 90 tonnes (89.6 tonnes) assuming it was like oversized version of Diplodocus carnegii. |

I won't say I can't be seriously wrong with my approach here but this is what you get if you scale the largest mandible of Gigantopithecus with the only concern being that the length of the teeth matches up. All the larger reconstructions seem to want to make the jaw fit in height, not wanting to consider the possibility that it might just be a big jawed creature. The original orangutan skull is there to illustrate the probable difference in the depth of the jaws. Pei & Li (1958) is the source of the photographs of the jaw, there's also measurements and it doesn't strike as that big, yes, if you look at the depth of the jaws, behind the p4 is 80mm in this mandible compared to 40mm in the gorilla they are comparing it to, you get the idea that it was immense, twice as big as the gorilla, but look at the other measurements, length from I1 to M2 is 101.3mm vs 85mm in the gorilla, a difference of only 19%, the size of the M3 is 21.9mm by 17.5mm, only 17% longer and less than 7% wider than that of the gorilla, there's bigger teeth of Gigantopithecus, as much as 15% larger than those of the mandible or so I've heard but assuming it's jaw was big for its head (as seen in for example, Paranthropus) I can't see how you can get a 3m tall ape (which btw, will weight close to 900kg, not 540kg, if based on gorillas assuming 170cm tall and 160kg are average) |

Ptychodus is often missed when we talk about big critters.  |

I have never heard of this one before, I now had to look it up. Is it true that this genus (probably a small species) survived the mass extinction in the end of the Cretaceous?

It seems to me that it disappeared more or less at the same time than Cretoxyrhina, possibly outcompeted by the shell-crushers mosasaurs like Globidens.

Damn, I was not even aware there were such huge Hybodontids.
